[Premium-Rx] WJ-DRO-333

[David Schofield]

Hi All,

Happy new year.
Does anyone out there have a copy of the schematic diagram for the DRO-333 PSU.
Mine has given up the ghost rendering my WJ-RS-111-B-!2 practically unusable without the DAFC feature of the DRO.

As far as I can tell I have the +/- 5v, and a -15v rail, but what I am guessing should be the +15v is nearly dead, and dies completely as soon as I connect the bulk store cap.
The PSU is on a seperate plug in card, and I'm sure I can figure it out, but it would be much easier with the schematic.

I have a partial manual for the counter section, but nothing for the PSU / RF sections.

Once again thanks in advance for any help,
Dave.S.
